Many different patterns arise during the course of hand development. | Many different patterns arise during the course of hand development. Once a hand reaches tenpai, being able to interpret the hand's available winning tiles is a vital skill. If a player does not correctly read their winning tiles, they may miss a valid win, or they may commit a [[chombo]] with an illegal win call: either by calling a win on a tile that does not complete the hand, or calling [[ron]] while [[furiten]] due to a tile that they did not realize would complete the hand. | ||
The most commonly occurring wait patterns have been given names, to make them more easily recognizable. More complex waits can arise involving a large number of potential configurations of the hand. This is especially true of hands with a large number of tiles in the same suit, most notably those aiming for [[chinitsu]]. Knowing the basic wait patterns also helps to combine them to interpret complex hands, which may have as many as 8 weights (not counting the special cases of [[chuuren poutou]] and [[kokushi musou]], which are easily recognizable). | |||

During hand development, it is important to understand the hand's machi for two reasons. The first is that, when trying to bring a hand to tenpai, a player will want to maximize the number of available tiles to bring them closer. Doing this requires interpreting the patterns of potential groups in a similar manner to finding tile waits in a tenpai hand. The second is that furiten is best avoided, and so a player should avoid making discards that would leave them furiten once they reach tenpai. This can be a particular challenge when developing single-suited hands that may have a large number of different waits. | |||

These combinations involve patterns that do not have specific names. Instead, they use combined forms of the other patterns. Furthermore, they mostly consist of consecutive, or closely consecutive, numbered tiles. Recognition of these patterns can produce some significantly powerful waits, which may be immune to [[suji]] and have large numbers of waiting tiles. | These combinations involve patterns that do not have specific names.

=== Hadaka tanki === | |||
{{main|Hadaka tanki}} | |||
'''Hadaka tanki'' refers to when a player has made four [[naki|tile calls]] (other than [[shouminkan|added kans]]), meaning that they only have one hidden tile left in hand. The hand is necessarily tenpai with a tanki wait. Such a hand is very difficult to defend with, because the player will only have two tiles to choose from. | |||

If there is only one wait, this means that the other three copies of the winning tile are all in the player's hand, in a discard pool, in a [[naki|called]] group, or visible as [[dora]] indicators. If there are multiple waits, this means that all but one of them must be completely used. In English, this is commonly known as the '''hell wait''', a literal translation of the Japanese. | ||
